SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 228,789, dated June 15, 1880.

Application filed March 23, 1880. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL L. S'rooKBER- GER, of Rochester, in the county of Fulton and State of Indiana, have invented certain new and useful Improvements in Spring Bed- Bottoms; and I do hereby declare that the following is a full, clear, and exact description of the invention, .which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention has relation to bed-bottoms; and it consists in the improvements in the construction of the same hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan view of a bed-bottom embodying the improvements in my invent-ion. Fig. 2 is a side elevation with the head-rest shown in two positions, one being in dotted lines. Fig. 8 is a perspective of the adjustable links which are applied to the wires that connect the springs. Fig. 4 is a detail view of a single spring and the staple by which it is connected to the slat.

Referring by letter to the drawings, A designates the cross-bars, to which the longitudinal slats B and the extension-arms O are secured. A head-rest frame is formed by hinging slats D to the slats B at E, and connecting their upper ends by a crossbar, F. Arod, G, runs through the slats D and secures a cross-bar, H, thereto by means of long arms I I. The cross-bar H works in a rack formedin the upper faces of the extension-arms 0. Short arms J J are pivoted to two of the slats D, and are employed to support the head-rest when the long arms I are nearly parallel with the extensionarms O, to relieve said long arms from unnecessary strain when in said position.

Helical springs K have their points inserted in perforations in the slats B and D in the usual manner, and a staple, L, is employedto secure the first coil of the spring K to the slat, 4

thereby giving it a permanent fastening. The upper end of the wire that forms the helical spring is looped over the coil next below it, in the usual manner, to complete the spring.

Wires M are looped to the top coils of the springs K, and connect the entire series of springs on each slat B and D, except at the hinge or connection between the head-rest and the bed-bottom proper, where short wires to b c d are linked together and connected to the springs K, as shown, to form a hinge-joint in connection with the links N. The links N are composed of two hooks, cfthe former upon the short arm, and the latter upon the long arm, of an irregular U-shaped piece of wire, similar in some respects to what is commonly known as a pot-hook, except that the long hook of the pot-hook is provided with an additional hook. These links N are employed to tighten or loosen, as the case may be, the wires M, and are constructed adjustably, in order that when the slats B and D, which are secured to the cross-bars by screws, are moved, to cause the bedbottom to conform to a larger or smaller bedstead, the links may be changed to keep up the proper tension between the springs K.

The hinge-joint between the slats B and D is composed of a staple, h, and eyebolt i or two interlinked staples may be used.

The springs K at the foot and head of the bed-bottom are placed farther from their fellows than those nearer the middle of the bottom, as greater weight comes near the middle.

Having thus fully described my invention,

what I claim as new and useful, and desire to SAMUEL STOCKBERGER.
